Bottineau Grain Train

Station sign Bottineau

In the summer of 1991 I took a trip to North Dakota with my brother, sister, mom and stepfather to visit my grandparents at their home in the quiet town of Bottineau. We caught the county fair, played at the lake, visited the family farm and played lots of card and dice games. Even thinking back to the pre-internet world that probably sounds boring, but my grandparents were a fun couple who loved to laugh and dote on their grandkids.

After our vacation concluded and we were about to leave, I chose to stick around and hang out with my grandparents for another week. I had graduated high school and didn't have anything pressing to do that next week, so why not? I'm really glad I was able to spend that time with my grandparents and get to know them as a young adult about to start college.

Anyway, there wasn't a whole lot going on during the lazy days so I chose to grab my sketch book and draw. I was going to be starting on a degree in fine arts in a few weeks so I was determined to draw what I could around town.

Like many small towns in North Dakota, Bottineau is home to a grain elevator complex situated alongside a railroad branchline. It wasn't long before I was drawn to the facility and began to study it. I took in the cylindrical and prismatic structures, the piping and wires connecting the various buildings, the contrast of the older sheet metal clad wooden elevator and the modern slipformed concrete silos and head house. Some things I can still remember clearly: the coolness of the shadows against the radiant concrete in the high sun and the ripples and waves in the slipformed walls when the evening sun set the buildings afire with red light.

And then one morning a train arrived.



Two geep thirty-eight types pulled fifty-two empties into town followed by a caboose. The train rolled into town quickly, then paused and started off again. The crew cut the crossings and tied the train down in four cuts, then stashed the power behind the depot. Before I knew what was going on the crew hopped in a taxi for a ride back to Minot.

In Texas I was used to the trains near my house flying by on the main, or coal trains struggling up the hill, or when things would get congested holding off crossings waiting for a light to get into town. The trains I'd see in Saginaw seemed static as we'd fly over the yards on the freeway. Even the jobs working the elevators and mills seemed to always be at lunch. I certainly hadn't seen anything like this.

ILSX 1366 and BN 454511

There wasn't much down time before the elevator crew fired up the old SW1 and started spotting cars in cuts of three at the barley house and at the durum house. As each car was loaded the switcher shoved them down the storage track, filling it up and eventually having to cut the crossings. Throughout the day and into the next the process repeated until the loaded train was set up in four cuts ready to be put back together and air tested.

I missed the train getting put back together, but I did see the caboose roll away behind the train and disappear into the twilight as the crew dragged it through the fields of grain down to Rugby to rejoin the main line.

It occurred to me that this process repeated itself over and over again. There was no time to rest, not for the rail crews that brought the empties in or took the loads out, not for the drivers bringing tractors, pickups, wagons and semi-trailers full of grain to the elevators, and certainly not for the switch crew at the elevator, who now had given up their switch engine duties to join in the effort to refill those silos.

Trucks lined the streets waiting for their turn through the head house. Fans and motors and machines made a constant droning sound around the complex. Clouds of grain dust floated in the air tinging everything with gold. The town was filled with that warm scent of cut summer grass.

21 years after the merger and still seeing Big Sky Blue

I had sketched and I had photographed and I had taken notes. I had a record of the locomotives, the railcars and the caboose that came to town and left. As many times as this process must have happened in towns across the midwest every day it seemed really insignificant. But those are the things nobody ever seems to take down, and soon they fade away as if they never happened. Two small town elevators combine into one complex. One town thrives and one fades away. Whatever would happen I wanted a record of that week.

Besides pre-merger hoppers, BN was grabbing every retired co-op car they could

It wasn't long before I began to make models based on those photos and notes and sketches. I soon became aware that exact models simply weren't available for most of the cars. And by exact, I mean as far as I knew there were rib side three bay hoppers and there were cylindrical shaped three bay hoppers. I could tell there were differences between many of them - some "missing" ribs in key places, some with high or low sides, some with a barrel shaped body and others almost completely cylindrical like a tank - but I didn't know how the differences broke down into capacity or manufacturer. But over time two things happened: I learned who made which car and manufacturers like Accurail, Intermountain and Model Die Casting brought out models to supplement the Athearn Pullman Standard and ACF hoppers that made up my first attempts at this train.

I took a crack at the caboose using a factory painted Athearn model. I eventually realized the Athearn model is too short, that it's a flawed model of a Rock Island caboose and not much of a match for the BN caboose I saw. Eventually I bought an Atlas caboose. Much better!

Atlas caboose modified with one of my 3D printed cupolas

Same thing with the locomotives. I bought two Athearn GP38-2s, one in BN green and one in Conrail blue. I fired up my airbrush and coated everything with a cloud of mud colored dust. It was brutal. Those locomotives eventually got stripped and repainted, then again stripped and cut up to become a pair of Mopac GP38-2s I still need to finish... I found a shell at a train show that looked pretty much how I remembered the ex-Conrail geep, so I bought it and found a drive for it. I picked up an Atlas GP38 decorated for BN later on.


Time for some updated photos!

Over the years I've replaced nearly every car I originally bought to make a model of this train. Some of them have been repurposed into models for this train and some for other subjects. More manufacturers have produced even more models, so I'm able to dial in the models closer and closer to the real thing. I even became a manufacturer myself of sorts when I worked up parts to model the caboose more accurately. I've covered some of the cars modeled in my blog previously, here, here and here.

To this day, nearly twenty-seven years later, this train remains a work in progress. I'll probably never finish modeling it. But by pursuing it, I keep it alive. I keep that summer alive. Making big bets at the card table in my grandma's house doesn't seem that far away.

My brother and I, both of us are engineers now

Now that I've been an engineer for some time, I can relate so much to that crew that tore into town, cut that train up and flew back to Minot in the cab. How many times have I done the same thing itching to get out of the seat and make it home for some time with the wife and girls before they go to sleep? Yes, you still have to dot all the I's and cross all the T's and do it safely, but an experienced and motivated railroader can do it quickly.

The older I get the less I rush like that. There's too much you can miss if you do. You end up doing it twice or more unless you take your time and move with purpose. You only learn that the closer you get to finishing something, when you can finally see your mistakes, missteps and oversights.

Who knows? Maybe one day I'll eventually get it right.

Cotton Belt EV Caboose 41

The previous post covered the other "test" caboose I built when I began developing the concept of a 3D printed modular caboose kit. The prototype for this model was the inspiration for the whole caboose project. Like some standard cupola cabooses of Norfolk & Western and Great Northern, Cotton Belt's extended vision cabooses had the cupola side windows placed at the corners. Although it is possible to modify an Atlas caboose to represent this unique variation, I decided instead to try my hand at 3D printing a replacement cupola.

With the memory of kitbashes of a Frisco extended vision caboose:




...and one of Mopac's distinctive extended vision cabooses fresh in my mind:



...it wasn't long before I decided to print a new roof, ends and sides to save myself the trouble of cutting up the Atlas model. And so began - innocently enough - what has become a quest to be able to model nearly any version of the International Car Company's extended vision caboose.

Since the process was described in the previous post, I will let the photos do the talking here for the most part.














This was the first cupola I designed for this caboose. It has an opaque, white appearance that is the result of washing it in isopropyl alcohol to remove the waxy residue that's part of the printing process. Unfortunately, the alcohol also had the effect of distorting and shrinking the part. I also discovered that the alcohol made the part brittle at the same time I discovered the shrinkage. When I tried to fit the cupola to the modified Atlas body it split the cuopla. I printed another version of this cupola design and that's what you see on the model. 






After experiencing an alignment issue between the cupola and the printed body (which occurred because I didn't include any keys or tabs so the interior would remain clean for detailing), I revised the early higher cupola design to eliminate the sidewall extensions originally designed for the Atlas body and incorporated the additional body height into the sides. This design change means the higher cupola cannot be easily modeled using the Atlas caboose without modifying the body to include the side extensions, but it really isn't a difficult problem to solve for the motivated modeler. I couldn't see why my design needed to suffer to accomodate the Atlas body when I had no intention of using it for future builds. This change was carried out through all affected models in my product line. If you look closely, you can see the area underneath the cupola where I had to use Bondo to fill in the misaligned areas between the cupola side extensions and the sides.











I painted this model with a brown paint mixture I tried to match to an Athearn Genesis caboose. I started with Model Master Rust and mixed in some burnt umber and burnt sienna until I was satisfied/gave up. The orange ends were much easier: they are Model Master Go Mango. The window frames were painted the same as on the Santa Fe caboose. 








Just as with the Santa Fe model, I'm happy with this one. I would like to see the printing process get a little better and cheaper, but in the end I got much more than I had hoped for when I originally dreamed up the idea of printing rather than kitbashing this model's cupola. 


Highball!

Santa Fe EV Caboose 999700

This caboose was built using an Atlas HO scale extended vision caboose as a starting point and with 3D printed sides, ends, roof, cupola, underbody and roof details. I painted it with Model Master enamel paints and lettered it with Microscale decals. The prototype was distinctive for being the only extended vision caboose to wear the color scheme of the proposed Southern Pacific Santa Fe Railroad known as Kodachrome or Shouldn't Paint So Fast.

Here are the 3D printed parts:







These photos show the body assembled, a process which is pretty simple. I began by aligning the correct end to the correct side applying "tack weld" dots of CA adhesive (super glue) from the inside of the body, then running a bead of glue along the inside of the joint once the fit is satisfactory. I repeated the process with the remaining end and side, then assembled the two L-shaped assemblies into a four-sided box. Finally, I aligned the roof parts to the opening for the cupola and secured them in place.

On this model and the Cotton Belt model no starter holes or grab iron ends are present, so all the wire parts were added using makeshift paper templates. I'm sorry to say it looks like it. But the good news is I revised all the models after assembling the two basic bodies so that each one is equipped with starter holes and grab iron ends appropriate to each prototype. In fact, I would say I learned a lot with these two models so that no others using this design would be so primitive. 








At this point I decided to replace the Atlas steps and crossover platform with Moloco parts and styrene sheet. Although the Atlas steps are pretty close to the Santa Fe prototype other than the number of steps, there is a clear difference between the Atlas part and earlier cabooses such as the Cotton Belt prototype that is the subject of the other build I was working on in tandem with this one. Since I would have to do the work anyway I decided to do it for both models. At this time I had primed the model with Model Master primer, which makes it much easier to work with and photograph than the unpainted translucent model.













The average end user of 3D printing services such as Shapeways is able to produce some really nice parts at this time, but to purposely leave out any mention of the weaknesses of this process as it is today would be dishonest. In the interest of full disclosure, take a look at the "ridges" in the roof running lengthwise in the photo below. Although I think I have a pretty good idea what causes this effect and how to avoid it, it sometimes still shows up. I was able to sand the ends of the roof and the tops of the embossed areas to try to minimize the appearance of the ridges but it's not completely effective. 




Finally, here is the model painted and decaled. I used Model Master Chrysler Engine Red, Insignia Yellow for the body and Light Ghost Gray for the aluminum window frames, followed by a drybrush of aluminium over the gray and black for the window gaskets. The trucks are painted with a mixture of black, burnt umber and gray.









It still needs light weathering and final details but that will have to come a little later. I have too many more of these projects to finish, not to mention the CAD for additional projects. It's not a perfect model by any means, nor was it an inexpensive one, but I think it is a good representation of the prototype, one that's not easy to obtain in HO scale.

Highball!
